Realy ELI5 –

Imagine you drop some spaghetti on your white shirt. It will stain it. You can get some soap and a brush and scrub it, over and over until the stain is less visible, and maybe even gone. But doing so will cause the shirt to erode or tear. You’ve damaged the fabric.

That’s what happens to your teeth (and gums), you’ll damage them. There are other things like whiteners to help do it without the excessive scrubbing. Like the Tide-to-go pens… helps with stains without the extra scrubbing.
